We used to know how to know. Get some experts, maybe a methodology, add some criteria and credentials, publish the results, and you get knowledge we can all rely on. But as knowledge is absorbed by our new digital medium, it’s becoming clear that the fundamentals of knowledge are not properties of knowledge but of its old paper medium. Skulls don’t scale. But the Net does. Now networked knowledge is taking on the properties of its new medium: never being settled, including disagreement within itself, and becoming not a set of stopping points but a web of temptations. Networked knowledge, for all its strengths, has its own set of problems. But, in knowledge’s new nature there is perhaps a hint about why the Net has such surprising transformative power.
